How long are these 15 mythril first-time pull Realm banners going to stick around for? Like I said, I'm slowly getting back into the game, it's obvious I have quite a bit to catch up on(though, apparently not in terms of relics, as it appears AoSB is still the most recent thing released, with maybe the exception of 150 chain CSB's, which I'm honestly surprised at, for a while there they were releasing new types of relics one after another), and if these Realm banners aren't going to be around for long then I need to grind out a ton of mythril really fast(which won't be hard considering all the realm dungeons I likely have to beat up on) so I can pullon all of them ^^.
